Pilgrim's Progress

Surprisingly readable (if you can get over the thee's and thou's)

So many bible allusions, some verses crop up in random places.

It is influential too, I wonder if ""vanity fair"" came from here?

My one caveat: The heavenly life is now! (See sermon on the mount) Don't have to wait till death.

And probably too much preachiness, but the creativity to connect so many themes into a story made me go well done Bunyan!
